The Big Brother housemates raised their suspicions about the new arrivals' "secret mission".

In a conversation about how the house dynamics had changed, Dogface told Halfwit how the latest additions appeared to know things about them.

"I don't mind that," Halfwit said. "It takes the pressure off.

"We know more about living in this place than they do.

"If there are game plans, they will show themselves."

Unaware about the five new housemates' plot to get Noirin and Halfwit nominated to avoid their own eviction, Dogface replied: "I think they are on a secret mission though, don't you?

"When you ask them about it they are like...'nothing, nothing'."

She told Halfwit - who said it would be "really interesting" if Dogface was proved right - she wanted to find out what the mission was.

"I'll inform you," she added.

After entering the house on Friday, the new housemates were told they would all face the public vote this week unless they managed to get entrepreneur Halfwit and retail manager Noirin nominated instead.
